To all whomfz' concern.' y Beit known that I, Simmer. J. S'rrnv,I acitizen of the United States, and a resldent of Greenwood, inthe countyof Leflore and State of Mississippi, have invented a new and ImprovedAttachment for Pneumatic Tires, of which the following is a full, clear,-and eXact description.

My invention relates to a non-skid, puncture-proof protector adapted tobe applied to a pneumatic tire, and the invention has for an object toprovide a protector composed of annular series of plates having nonskidelements and hinged together, certain of the hinges being formed topresent end members adapted for connection with the elements employedfor fastening the protector to a wheel.v Y

The above and other objects as will appear are attained by the novelconstruction and arrangement of parts hereinafter particularlydescribed.

Reference is to be had to the accompany ing drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 1 is a plan view of a portion of a device embodying my invention;

Fig. 2 is a longitudinal section on the line 2-Q, Fig. 1;

- Fig. 3 is an enlarged section on the line 3 3, Fig. 1; K l

Fig. et shows'in side elevation a portion of a wheel with a portion ofmy protector in place;

Fig. 5 is a detail showing in cross section a portion of the wheel rimwith the means of securing the fastening elements to the rim.

In carrying out my invention in practice, a series of plates 10 areprovided adapted to lic on the out-er surface of a tire A as in Fig. 4:.To provide non-skid members the' several plates in practice are providedwith punched up protuberances 11 and also, the side edges of the platesare provided with out-turned flanges 12 which in addition tocontributing to the non-skid character of Vthe protector Serve tostrengthen the plates.

The plates are hingedly connected to one another. Alternate hinges maybe of known form involving aldining knuckles 18 and a hinge' pin 14passing therethrough. Others et the hinges, preferably alternate ones,conE lsist of tubular yedge portions 15 on adjacent transverse edges ofthev plates, the adjacent tubular/members lying in close relation andparallel. Through tubular edges 15 of a pair extend double pins 16 whichare given a form to adapt them to connect with fastening members adaptedto be fastened to the wheel on ,which the protector is employed. Eachpin 16 is formed of a continuous length of rod or. wire returned onitself,

thereby presenting a loop 17 at one end of the double lpin projectingbeyond the side e Oes of the plates 10. At the opposite end theterminals of the double pin 16 are return bent in hooked form as at 18disposed beyond the adjacent-side edges of the plates.

The ends of the double pin 16 presenting Y respectively a. loop 17 andhooked terminals 18 are utilized for connecting with the protector thefastener elements which may consist, as indicated, of lengths of chain19. At'onc side of the protector the ring 20 of a fastener element 19passes through the loop 17 while at the opposite side the ring embracesthe double pin 17 and is held aga-inst displacement by the return hookedends 18.

The elements 19 lat the inner ends may be made fast to the wheel inV anyapproved manner; as here shown each element 19 eX- tends to the interiorof the rim B of the wheel and is secured by a. thumb screw 21 in saidrim and adapt-ed to be given a quarter turn. With the head of the thumbscrew parallell with the links, the inner end link of the element 19 maybe passed over said head after which the screw is given a quarter turnto dispose the head of the screw transverse to the chain link asindicated in dotted lines in Fig. 5. By providing pins 16 of a form toconnect with the fastening j elements, the use of separate means on theprotector for connecting said elements is avoided. Y l

I would sta-te in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limitmyself strictly to the mechanical details herein illustrated sincemanifestly the same can be considerably varied without departure fromthe Spirit of the invention as defined in the appended claims.k

I-Iaving thus described my invention, I

claim as new, and desire to secure by Letters Patent: Y l

1. A tire protector including a series of protector elements,` hingemeans uniting said elements, Said hinge ineens zit certa in of the hingeconnections comprising tubular edges on adjacent elements and parallelwith each other, and double pins therein, said pins being united at oneend by an integral loop, the terminale or' seid pins at the oppositeends thereof being returned in hooked forni in opposite directions;together With 'tustener elementsY adapted to be secured to :t Wheel, andringe` on said elements and connected with said pins, those rings at oneeide of the protector passing through the loops of the pins, and thoserings at the opposite side or' the lprotector embracing seid pins inwardoit the returned termina-ls thereof.

2. A tire protector including` n, series of protector sections, anddouble hinge pins linking adjacent protector `Sections together` saidpine presenting transversely disposed parallel ineinhers hinged to therespective ends of the `adjacent sections; together with feet-enerineens to secure the protector on :iy Wheel7 the ende or said doublepins having members secured to said fastener Ineens.
